  • This study was conducted to evaluate the breadmaking characteristics of white bread when rice bran (RB), fermented rice bran (FRB) and rice bran oil (RBO) were added to the dough. Addition of RB to dough generally showed a decrease of the bread volume and increase of the bread weight which is related to the comparative decrease of gluten in the dough. Addition of RB also showed a decrease of lightness with yellowish color of RB and showed some rheological changes in dough. However, up to 5% RB addition, the dough showed a similar property of breadmaking with giving functional benefits compared to the control. Moreover 5% FRB addition to the dough improved the taste, flavor, and texture important to quality of bread. Substitutional use of RBO for shortening in dough result in comparative decrease of volume of dough. Addition of yellowish RBO influenced the increasing yellowness score, hardness, gumminess and brittleness, which is disadvantageous for the quality of white bread. However up to 50% RBO substitution for shortening made little rheological differences compared to the control. The 50% RBO substitution for shortening increased the score of flavor in sensory test even if there was an unfavorable quality point of white bread caused by a decreased volume and an increased hardness. From these results it could be suggested that the proper use of RB, FRB and RBO in breadmaking could improve the taste and flavor, giving beneficial function originated from rice bran to white bread.

  • We studied suitable dough formula for yeast-raised breadmaking using frozen dough prepared by straight no-time method, centering around breadmaking quality. The most suitable dough formula based on 1,000 g of wheat flours was as follows : compressed yeast ; 30 g, sucrose ; 50 g, salt ; 20 g, shortening ; 40 g, potassium bromate ; 75mg, L-ascorbic acid ; 200mg, yeast food ; 3 g, vital wheat gluten ; 30 g, calcium phosphate, monobasic ; 400mg, sodium stearoyl-2-lactylate ; 8 g, water ; 680 g. Breadmaking test employing this formula showed that gassing power and fermentation time were suitable and higher specific loaf volume was obtainable. By using much emulsifiers and dough conditioners, frozen injury of dough was controlable in spite of the addition of more content of water(68%) than that of water (62%) obtained from the farinograph data.

  • The qualities of bread and change of phytic acid during breadmaking with whole wheat flour were investigated. The ratios of ash contents in wheat flour and whole wheat flour were 0.41% and 1.57%, respectively. The ratios of fiber contents in wheat flour and whole wheat flour were 0.14% and 1.83%, respectively. In amino acid analysis, glutamic acid was determined to be 32~36g/100g protein, which was the highest. Lysine, glycine, arginine and aspartic acid were higher in whole wheat flour than those of wheat flour. Proline, glutamic acid, and phenylalanine were higher in wheat flour than those of whole wheat flour. The ratio of phytic acid content in wheat flour and whole wheat flour was 0.312% and 0.734%, respectively. The content of phytic acid during beadmaking was decreased approximately 65% after proofing, while this was almost constant in the process of oven baking. The content of phytic acid in bread with 3% yeast had less hydrolysis than that in bread with 5% yeast during breadmaking. The phytic acid content in the 0.1% yeast food was decreased more than the 0, 0.3, and 0.5% yeast food groups. As the amount of whole wheat flour increased, the volume of bread was decreased, and color became dark. The sensory evaluation was showed the quality of bread to be the highest when the amounts of coarse whole wheat flour and fine whole wheat flour was 20% and 30%, respectively. Though the amount of coarse whole wheat flour and fine whole wheat flour were increased up to 30% and 50%, respectively, external characteristics of bread was remained in normal.

  • The effect of oxidants, gluten and gums on breadmaking quality of wheat-purple sweet potato(Ipomoea batatas) composite flour were studied. Alveograph tests of doughs showed that all additives increased the P, L and W values. Of these additives, L-Ascorbic acid, gluten, carboxy methyl cellulose have a significant effect on alveogram indexes. SEM showed that the dough added with additives changed some what in appearance when compared with the control. When oxidants was added, the doughs discontinuous gluten film were observed. No significant differences ,were evident in bread crumb color among the additives. And textural characteristics of bread crumb were influened by adding additives. Breads containing additives showed an increase in max weight, strength and hardness and a decrease in springness and cohesiveness. Average enthalpy values for all bread crumb after 7days increased with storage time. However, addition of additives decrease the rate of staling slightly more than that of the control. Addition of L-Ascorbic acid, L-Cystine, carboxy methyl cellulose and hydroxy propyl methyl cellulose increased the loaf volume significantly, and with except potassium bromate bread scores were acceptable.

  • Although the technology of breadmaking simply goes through the process of mixing, fermentation, and baking, it is very hard to make a same product every day. The reason is that baking science begins with the very first process of breadmaking which is mixing, and every steps and working environments are so closely connected. The baking science has developed in short time since the theory of fermentation has released. If you check the development of baking technology synthetically, it is consisted of the discovery of nutritional and functional ingredients, the optimization process of new machines, and the maintenance of the quality as fulfilling social demands. Because the baking business is making and selling the product, baking itself is a business, and it has the form that manufacturing and service business coexist. In today's current domestic bakery market, the supply exceeds the demand. Moreover, the concept of bakery itself has been changing from the fixed image of bakery which is selling the bread to the differentiated bakery with others. As we look at the general bakery's trends, it is focused on going back to the basic or traditions, going to the functional, and working with automations. To conclude, the baking has a long history, but it actually has the short history in the technological development. Baking business can be viewed as the simple business, but many factors are related to the business. It has a few basic kinds of products in baking, but it has diverse kinds of products with the base of infinite creativity. Even though it is physically a hard working business, it is also a business that can face with fun. For managing a bakery, finally, the differentiated strategy with other bakery that maximizes the customers' value is needed.

  • Physicochemical properties of bread as influenced by the addition of sweet pumpkin powder (SPP) were investigated. Freeze-dried sweet pumpkin was ground, sieved through a laboratory sieve and a fraction with particles less than $250\;{\mu}m$ was used. Amount of SPP added to the bread was found to affect the bread quality significantly (p<0.05). Loaf volume and weight of the control were significantly higher than others (p<0.05) and decreased significantly (p<0.05) with the addition of SPP. In other words, the enrichment of product with SPP decreased bread volume and weight without significant changes in the moisture content. There were distinctive color changes with the addition of the powder: L- and a-values were reduced but b-value was significantly increased (p<0.05). The hardness, springiness, and gumminess of bread were found to increase with the addition of the powder. Consumer test indicated that bread contained with 3% SPP had the highest overall acceptability score while 1 or 5% addition produced an acceptable quality for the bread.

  • Breadmaking is a complex system in which many variables govern the production of acceptable bread. Lipids, a minor component of wheat flour, function importantly in bread-making. Shortening, or fat, is one of the essential ingredients in commercial baking. Beneficial shortening effect depends on type and quantity of lipids present in wheat flour and also on wheat flour quality. Surfactants have been used in baking industry during last decade because certrain surfactants can replace shortening and/or natural flour lipids. A proper combination of lipidshortening-surfactant is more useful in the production of specialty breads such as whole wheat breads, high protein breads, high fiber breads or even non-wheat composite breads rather than in the production of regular white breads. This presentation is a review of recent studies on the contribution of flour lipids, shortening, and surfactants, alone or in combination in the production of breads; illustrations are mainly from data obtained in the author's laboratory.

  • The aim of this study was to investigate the effects of mulberry extracts on the physical characteristics of dough and the quality characteristics of oddi bread. The peak time of all experimental doughs except ME 25 (25% mulberry extracts) was suitable for breadmaking. The fermentation rate was decreased in accordance with the addition of mulberry extracts and the pH of the dough was decreased from 5.96 to 5.29. L values of oddi bread decreased with increasing mulberry extracts whereas, a and b values increased. The sensory evaluation indicated that crumb and crust color of the control bread was the brightest among the experiments. Flavor and taste was high as the addition of mulberry extracts. The overall acceptance was preferred at ME 25. Since the outcome of the mixograph at ME 25 tended to be low in bread-making, the utility of mulberry extracts at 20% (flour basis) was appropriate.

  • This research investigates the quality characteristics of bread added with honey. The overall effects of honey on white pan bread were examined in terms of mixograph, fermentation rates, pH levels, TPA, colorimeter, water activity, hardness and moisture content of bread through different storage periods(1, 2, 3 days) using sensory evaluation. According to mixograph, all the samples were found to be proper between 3 and 5 minutes of peak time and their peak values were at the level of 60%. Also, HL100 had the highest fermentation rate and fermentation persistence from 60 min to 135 min. HL100 showed the lowest pH level in ingredient, dough, fermentation and crumb, and the highest specific volume. TPA analysis showed that HL100 had the lowest hardness and the highest springiness of all. And HL100 was the lowest in hardness(i.e. highest in softness) and had the highest moisture content after storage of 72 hours. Preference test showed that HL100 got the best texture, flavor, mouth feel, taste and overall acceptance. In these results of experiment, honey affects the quality of dough and bread, and liquid honey could be used as a substitute for sugar in breadmaking.

  • Effects of native and RS-3 type resistant starches prepared from autoclaved-cooled amylomaize VII(AVII) and normal maize starches(NMS) on the rheological and baking properties of wheat flour dough and quality of breads were investigated. In farinogram, water absorption and dough development time were increased, but stability was reduced by the addition of RS. The addition of native starches or resistant starch made from AVII to wheat flour improved the total volume and specific loaf volume of bread compared with the control(no addition), but the addition of NMS-RS reduced those. During the storage of bread at room temperature, the moisture content of control was decreased but those of native starch- or RS-added breads remained constantly. AVII-RS- or NMS-RS-added bread was evaluated to have good overall acceptability compared with control by elementary school students. The addition of enzyme-resistant starch to bread regardless of botanical sources of starch not only improved the overall acceptability and nutritional benefits but also improved the sensory acceptability.
